Oh, I do apologise, it turned out that my /bin/sh was dash after all so I got confused. Using non-$-prefixed variables inside arithmetic expansion was a bit of shell syntax [1] that I wasn't aware of. Sven: it was "OPTIND" => "$OPTIND" I was talking about, not the added spaces. It doesn't seem unreasonable to change mkvmlinuz to work around this dash bug (linked to by Gerrit) for now, though. Personally (and I suppose it's a matter of taste) I find it clearer to $-prefix variables even inside arithmetic expansions.
